Inspection
Full size inspection: dimensional accuracy, raceway hardness, axial clearance, radial clearance, axial runout, gear radial runout, gear accuracy, tooth surface hardness, rotational flexibility, appearance, documentation, etc.
Gear Heat Treatment
The raceway heat treatment of the slewing bearing is realized by induction heat treatment technology. Xuzhou Wanda Slewing Bearing has advanced heat treatment equipment (processing equipment and testing equipment) and scientific processing technology, so that the depth and hardness of the hardened layer conform to JB /T2300-2018 slewing bearing standard.
Quality Control
The company has passed ISO9001 Quality Management System, ISO14001 Environmental Management System certification and China Classification Society (CCS) supplier certification.
Three Coordinates
It is used to detect the straightness, flatness, roundness, cylindricity, profile, perpendicularity, parallelism, inclination,
coaxiality, concentricity, symmetry, position, compound position, curve profile, Surface profile, radial circular runout, radial full runout, end face circular runout, end face full runout, etc.
Measuring range：X=1000,Y=2000,Z=800mm;
Measuring accuracy：3.0 +L/250 µm（L:mm）
Ultrasonic Surface Hardening Layer Thickness Gauge
Imported advanced equipment is used to detect the depth of induction hardened layer on the surface of various steel materials(non-destructive testing). Hard layer depth detection after raceway heat treatment (no slicing, direct measurement).
The company has complete research and development, verification and inspection equipment, and currently there are more than 20 kinds of equipments in the factory, including automatic turret microhardness tester, microcomputer-controlled universal testing machine, metallographic microscope, magnetic particle flaw detector, digital ultrasonic flaw detector, bearing measuring instrument, Leeb hardness tester, ultrasonic surface quenching layer thickness gauge, three coordinates, etc. A variety of testing and control methods are used to escort the manufacture of high-quality products.
